IMPROVEMENT INLATHES FQR TURNING 'AXLES.

y I, ADAM J. Bowan, ofnibiououilw of nuwards, State of Illinois, have inventedcertain new and useful "Improvements in Lathes `for Turning Wooden `=Wagon-Axles, of which the `followiu g is a specification;

Nature and Objects1 of Invent/ion.

` My invention consists, first, in a certain com- A form desired', but receives in the operation the dish and gather` necessary for an ordinary taper-ended wagon-axle; second, in certain peculiar devices foradjusting and securing the tail-center of `the"lathe; third, in a peculiar devicefor chucking the axle, which adapts itself automatically to the axle after the latter has beenadjusted between the cenf ters 5 fourth, in a combination and arrangement of gearing for operating the cutters.

u i q General Description.

. the center of the head-block. It is adjustable by means of screw dand wheel E, and is `secured. in any position by set-screw F. A

spur-wheel, G, is iitted to the centerD in such a way that1 it" may either revolve upon the center or be fast upon it at will. A spur-wheel,

`Hg'driven by spindle `I and wheel J gears into wheelG. The .tail-center K is fitted to a block, L, which slides laterally, so as to adapt it for adjustment to,give thegather to the axle. `The block L slides within ablock, M, which, in its turn, slides vertically in the tailbioek c to `adjust the @Xie for the dish. The

block M issecuredv in .any position by the screw N, which adjusts it. The block L, which needs more rapid adjustment, is secured by the crank-nut P. rlhis block, or the cone in which it slides, is graduated,V to facilitate accurate adjustment, and itted with adjustable stops a, in order that any number of axles may be turned with the same gather without needing nice adjustment to theV scale, the stops resting on each side against the tail-block when the center is pushed over from one side to the other4 to finish both ends of the axle. The block M is alsograduated on the side, and a line is provided on the tail-block to permit nice adjustment of block M. The tail-block C is adjustable longitudinally to suit various lengths of axles by means of set-screw Q. The revolving cutter-head R is journaled at one end in bearing S, and at the opposite end in the center D. It is shown in the drawing operated by bevel-gearing Trbutit may be operated in any other preferred way. The cutters U are adjustable in their blocks .radially to give the required size to the axle by means of `screws b c. The blocks V, to which the cutters are secured, slide angularly in the y When the end is completed the full `length l of the taper the wheel G is allowed to run loose, when, by turning the hand-wheel J, the cutters may be run back. After one end of the axle is turned, and it is reversed or turned end for end in the lathe, it is necessary to move the block' L to the opposite side of the tail-block to that occupied byit when the viirst end was turned. The chuck, which prevents the axle from revolving while the cutters are turning it, is composed of dog f, crank-nut g, swinging and sliding dog h, and round bar t'. Thebar t' is secured to the bed of the lathe,

and-the dog h swings and slides upon it, so

that it (the dog) may adjust itself on the bar t automatically to suit any axle without defleeting the axle. The axle is secured between the dogs f h by nut g.

Claims.

l. In combination with a tail-block, C, constructed with a center, K, which is adjustable both laterally and vertically, the rotary cutter-head R U, connecting and operating as described, and for the purpose specied.

2. The combination ofthe tail-block C, adjustable blocks L and M, screws d and N, and nut P, as described, and for the purpose set forth.
